The Broad Applications of Dilatometers

A dilatometer measures dimensional change of a sample as a function of temperature or time under a defined temperature program, with near-zero applied load. It is suitable for solids, molten metals, powders, and coatings. These instruments are widely used across inorganic ceramics, metal materials, polymer plastics, building materials, coating materials, refractories, and composite materials. They serve industrial users as well as research and teaching environments. Typical measurements focus on thermally driven physical and chemical changes, including linear expansion and contraction, softening temperature, glass transition temperature, densification and sintering processes, and phase transformations.
